Abstract
In this paper, change of land cover and use type was first studied through interpretation of the two images (2007 and 2018), and then, dynamic evaluation of ecological service value in Southern Mountainous Areas of Jinan was made with evaluation system and equivalent factors built by Xie GD based on Costanza’s system. The results revealed that the area of bare land and grass land decreased by 4875.48 hm2 and 55141.56 hm2 respectively, on the contrary, cultivated land, forestland and building land has increased by 26915.671 hm2, 32261.31 hm2 and 1442.16 hm2 respectively. The ecological service value showed the increasing trend generally, among of which water conservation, air regulation, land protection, recreation have increased distinctly, which can be explained that the control develop strategies had taken action actively.
Highlights
The southern mountainous area of Jinan belonging to Mount Tai, is the ecotone of mountain and plain between Mount Tai and the Yellow River with southern high and northern low-lying
After preprocessing of image data, water, cultivated land, forest land, grass land, building land, bare land were distinguished according to the classification standard
The evaluation system of ecosystem service value and main equivalence factors performed by Xie GD [2, 3, 4] based on Costanza’s evaluation system were selected to evaluate ecosystem service of the southern mountainous area of Jinan in this paper
Summary
The southern mountainous area of Jinan belonging to Mount Tai, is the ecotone of mountain and plain between Mount Tai and the Yellow River with southern high and northern low-lying. This area is the main recharge area of spring water, water conservation area and one of the important ecological defences of Jinan city. The study area in this paper is mainly based on the "Protection and Development Planning for Southern Mountain Areas of Jinan City" posted by Jinan municipal government, which delimits the boundary north to south of central city of Jinan, south to Tai'an, west to Licheng, and east to Zhangqiu, covering an area of 226806.12hm, with a total population of about 6.1×105. The study area belongs to warm temperate monsoon climate with cinnamon soil and deciduous broad-leaved forest
